What kind of tax deductions can I claim?

that will depend on a number of things, are you single with no dependents or a dependent as a non dependent your non taxable income is $9500, as a dependent up to $5800 the purchase of the car will do nothing for you unless you itemize on Sch A, very unlikely the education credits are just that, reduce your gross income, that includes the interest you pay on the student loans, a limited amount and if you are a dependent your parents will claim some of your education credits(ie.tuition)

You can claim deductions on the expenses like interest on student loans, your home mortgage interest if any, any tuition expenses etc. If you do qualify for quite a few major deductions, you would be better off going for itemizing rather than standard deductions. Here's a complete list of itemized deductions that can help you decide on your deductions.

Car does not do much for you in regards to taxes but the student loan interest you paid up to $ 2,500 can be taken as an adjustment to income on the face of the 1040 or 1040A without itemizing. You should get a statement showing how much interest you paid from the outfit you were paying; make sure they have your correct address.
